Dear community, happy to share a brief community digest after a rather quite week including updates on Flink 1.9.2 and Flink 1.10, and the ongoing votes on FLIP-27 (New Source Interface) and FLIP-92 (N-Ary Stream Operator).
Flink Development ============== * [releases] Hequn has published the first release candidate for Apache Flink 1.9.2 and is waiting for votes and feedback. [1] * [releases] No feedback on the RC0 for Flink 1.10 so far. Still, I assume a first release (non-preview) candidate for Flink 1.10 is just around the corner as only a few blockers remain on the board for 1.10. [2] * [runtime] Piotr has started a vote on adding an N-Ary Stream Operator (FLIP-92). [3] * [connectors] Becket has resumed the vote on highly anticipated FLIP-27, the new source interface.

This only applies to users using Application Clusters (Job Clusters) prior to Flink 1.10 as these do not use a dedicated classloader for user code. Resolved in 1.9.2 and 1.10. [5] [FLINK-13758] [1.8.3] [1.9.1] As a user you can use Flink's distributed cache to make files available to all user defined functions running in the cluster. This did not work for files stored in HDFS for a while. Resolved in 1.8.4, 1.9.2 and 1.10.
